Abstract

Power system apparatuses are often deenergized for maintenance, followed by reenergization. Switching operations to change the network configuration are performed according to a predetermined switching sequence list. So far, a dispatcher in the power system control center manually makes up a switching sequence list in consideration of network conditions and security. In recent years, knowledge based approaches have been proposed and implemented in real systems. However, this sort of approaches tends to be expensive in real implementation. One of main causes of high implementation cost lies in the requirement of high performance computers.
In this research, we have developed an economical knowledge based system for supporting the power system operation procedure which can be implemented on personal computers. This expert system has the following characteristics:
(1) It can automatically make up a valid switching sequence list for any network configuration, and verify switching sequence lists by simulating the switching operations on the graphic monitor.
(2) It can also verify the knowledge base by dynamic verification technique.
(3) Two personal computers are linked by serial interface to simulate a control center. The display scrolling and the voice annoucement are also implemented on the system.
